Hi there, thanks for getting back to me. Yes we got tort from local couple who deffinately breed themselves, we have seen the parents of our tort many times (brothers & sisters also). I have taken your advice & sprayed the house, so i will wait & see if the whistle stops. We have a local vet who specializes in reptiles so i might pay him a visit when the weather is not so cold. just to make sure everything is ok.
Take care
